Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 6-17 fertile spikelets. Panicle open; linear, or oblong; 6-12 cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 18-24 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; glabrous. Floret callus pilose. Floret callus hairs 1.5 mm long.
Fertile
Spikelets comprising 5-7 fertile florets; with diminished florets at the apex.
